The world is not on track to reach its goal of limiting global temperature increase to 2°C, warned the International Energy Agency (IEA) on Monday.

Highlighting the need for intensive action in the energy sector before 2020, the IEA noted that the energy sector accounts for about two-thirds of global greenhouse gas emissions from burning fossil fuels.

“Climate change has quite frankly slipped to the back burner of policy priorities,” Marie van der Hoeven, IEA Executive Director said in a press release that accompanied the London launch of an IEA report, Redrawing the Energy-Climate Map. “But the problem is not going away – quite the opposite.”

“This report shows that the path we are currently on is more likely to result in a temperature increase of between 3.6 °C and 5.3 °C but also finds that much more can be done to tackle energy-sector emissions without jeopardising economic growth, an important concern for many governments,” van der Hoeven said.

Government and financial institutions around the world must pledge to invest at least US$40 billion (€30.6 billion) in renewable energy over the next 12 months as a way of fighting climate change, according to a campaign launched this week by the environmental NGO the WWF.

“We are running out of time,” says Jim Leape, director general of WWF International, launching the campaign Seize Your Power. “We know that if we continue to rely on fossil fuels we will face a future of worsening air pollution and an increasingly inhospitable climate. It is now our collective responsibility to commit to the future we want. We call on political and financial decision-makers to seize their power to make the switch to clean and sustainable renewable energy and end the inertia of coal, oil and gas.”

Anyone and everyone can sign the pledge on the WWF’s website to encourage governments and financial institutions to put their money where their mouth is, and promise greater funds for wind, solar and water power. The campaign will run in 20 countries around the world and be targeted at public finance, pension funds and sovereign wealth funds.

Wind energy doesn’t usually see much support from UK newspaper the Daily Telegraph, but this weekend the paper published a story based on National Grid (the UK’s electricity grid operator) evidence proving that wind farms do not need fossil fuel back-up for when the weather is calm.

“The National Grid has studied what actually happens in practice, with explosive, if surprising, results,” the paper said. “Between April 2011 and September 2012…wind produced some 23,700 gigawatt hours (GWh) of power. Only 22 GWh of power from fossil fuels was needed to fill the gaps when the wind didn’t blow. That’s less than a thousandth of the turbines’ output – and, as it happens, less than a tenth of what was needed to back up conventional power stations.”

That statement highlights another perhaps little known fact – fossil fuel power stations do need back-up. A fossil fuelled power station needs to shut down for repairs or maintenance taking many gigawatts of power offline with it.

The UK government will vote today on the ‘Energy Bill’ – measures to decide how the UK will structure its energy sector in the future, including a possible 2030 decarbonisation target. The target has been backed by an alliance of 55 energy companies, trade unions, environmental and faith groups – including SSE, RES, Vestas, EDP, Repower, Scottish Renewables and Renewable UK – and, last week UK Secretary of State for Energy and Climate Change Edward Davey called on the EU to set an emissions reduction target of 50% by 2030.

Leading business figure and member of the UK House of Lords, Lord Sugar, also backs a decarbonisation target. He said in a letter (‘cutting our carbon would help UK business’, 2 June) published in the Financial Times that “renewables companies have shown they are ready to invest in Britain, but they need to see a commitment from this government that they are serious. To create jobs here, they need real certainty – and that will require a proper “decarbonisation” target in the forthcoming energy bill,” he said.

Wind power in Africa is likely to experience a huge boost in installed capacity over the next few years, according to an African Development Bank (AfDB) study.

While wind power on the continent currently makes up only 1% of total electricity, or 1 GW, there is an additional 10.5 GW in the pipeline, the study, Development of Wind Energy in Africa, shows.

Africa is faced with the challenge of generating more power to meet existing and future demand as more than 500 million people on the continent lack access to electricity, the study says, adding at least eight African nations are among the developing world’s most endowed in terms of wind energy potential.

Noting that wind power is one of the world’s fastest-growing energy resources, the study said Somalia, Sudan, Libya, Mauritania, Egypt, Madagascar, Kenya and Chad have large onshore wind energy potential.

Exploring 76 African wind energy projects, the study found that only 24 are completed. Of the completed projects, the study said 74% are located in Egypt, Morocco and Tunisia – which collectively accounted for 99% of total installed capacity at the end of 2010.
